- If you are able to become pregnant, you will have a urine pregnancy test. The study staff will give you the pregnancy test kit at your scheduled visit, and will review and record the results of the test before you can pick up the study drugs from the pharmacy. The pregnancy test will be repeated at weeks 1, 4, 7, and 12 (or at the first follow-up clinic visit post-treatment) and 30 days after the study drugs are stopped .
